| That looks cool. A problem might be the water it scoops up unless the cannon is stored inside the airbubble. (Which is probably not what you want because penetrating the bubble just to enter the water would waste a lot of kinetic energy.)
Let's see, apart from a form of torpedo, I don't see anything that is really a possible weapon underwater with the exception of fired singularities. (which are so out of place here it's not even funny.) And as for the high speed thing, the only solution I can find is to slow down first.
I have a similar problem in my universe where the ships use a form of innertialess propulsion system. The only weapon that can keep up and do damage is a large missile with the same kind of propulsion system. To avoid getting their flightpath messed up by conflicting thrust vectors, the ships come to a full stop, fire and zip off. I suppose it could be similar here.
Another solution I just thought of. Instead of launching forward, drop the torpedo out of the back. As long as it is faster than the firing sub, it can float out of the bubble and then accelerate towards its target. (taking an appropriate curve to avoid the tailpipe of the firing sub of course.) That way, the sub can continue moving at full speed and your problem would be solved, I think. |
